+    I honestly don't understand the behaviour of the xclip process.
+    When not run async, this script seems to hang forever, I assume because
+    xclip is waiting for more input. When run async, even if the
+    abort_async_command call is omitted, the number of xclip processes in ps
+    output doesn't increase - i.e. it is somehow not a process leak?
+
+    Other long-lived processes do show the expected behaviour without
+    abort_async_command, and uncommenting it does limit the total number to 1.
+
+    So I'm leaving it like this. It works fine, evidently. If you understand
+    what exactly is up, open an issue.
